Learning Geometrical Concepts using Dynamic Geometry Software
نویسنده
چکیده
Dynamic geometry software promises direct manipulation of geometrical objects and relations. This paper reports aspects of a research study deigned to examine the impact of using such software on student conceptions. Analysis of the data from the study indicates that, while the use of dynamic geometry software can assist students in making progress towards more mathematical explanation (and thereby provide a foundation on which to build further notions of deductive reasoning in mathematics), the ‘dynamic’ nature of the software influences the form of explanation, especially in the early stages.

Children Learning to Specify Geometrical Relationships using a Dynamic Geometry Package
In order to understand the learning taking place when students use a dynamic geometry package such as Cabri-Géomètre, a particular focus for study needs to be on the learning mediated through employing such a resource. In this paper I describe how one pair of 12 year old students begin learning how to specify geometrical relationships in Cabri. I argue that, while Cabri provides certain element...
متن کاملBuilding Dynamic Visual and Logic Models with Geometry Expert
In this paper, we introduce a software, Geometry Expert, developed by us for automated geometry reasoning and dynamic geometry drawing. As a dynamic geometry software, GEX can be used to build dynamic visual models to assist teaching and learning of various mathematical concepts in an intuitive way. As an automated reasoning software, we can build dynamic logic models which can do reasoning the...
متن کاملResearching the Learning of Geometrical Concepts in the Secondary Classroom
Researching the learning of geometrical concepts in the secondary classroom presents both problems and opportunities. The specification of the geometry curriculum, the need to concretise abstract geometrical objects for classroom activities, the role of the teacher and the need to reconsider geometrical notions from different viewpoints are all factors which affect the acquisition of geometrica...
متن کاملThe Shaping of Student Knowledge
The focus of this paper is a software genre usually referred to as ‘dynamic geometry’ because of the ability of the user to dynamically manipulate geometrical figures created with the software tool. Using data from a longitudinal study of 12-13 students’ use of dynamic geometry software, the focus of the analysis is on the interpretations the students make of geometrical objects and relationshi...
متن کاملStudent’s Development of Geometrical Concepts Through a Dynamic Learning Environment
Geometry is one of the important areas of mathematics over the world. Geometry provides experiences that help students develop understanding of shapes and their properties. It enables students to solve relevant problems and to apply geometric properties to real-world situations. National Council of Supervisors of Mathematics endorsed that geometry was one of the ten proposed basis skill areas (...
